TRACTOR-WHEEL.

Application filed July 16, 1915.

T0 all whom t may concern Ie it known that I, Nens LINER OLsox. a citizen of the United States, and a resident of Highland Park. in the county of IVayne and State of Michigan, have invented a new and Improved 'Iractor-IYheel. of which the following is a full, clear. and exact description.

This invention relates to wheels and particularly to power or traction wheels and has for an object the provision ot an improved simplified construction which may be variously coupled up so as to have a direct drive or a slow or fast drive.

Another object in view is to provide a tractor wheel which may be adjusted for producing different speeds as may be desired.

A still further object in view is to provide a tractor wheel in which a plurality of inter acting gears are used for producing different speeds, a different set of gears being utilized Jfor each speed.

In the accompanying drawings Figure 1 is a side view of a wheel embodying the invention; Fig. 2 is a section through Fig. l on line '2-Q,the same being on an enlarged scale; Fig. 3 is a section similar to Fig. L) but showing the parts ditl'erently arranged for producing a diii'erent speed to that shown in Fig. '2; Fig. l is a sectional view through Fig. 3 on line l-4, the same being on a slightly reduced scale; Fig. 5 is a view similar to Fig. 4 but disclosing a different arrangement of gears to that shown in Fig. 4.; Fig. 6 is a detail perspective view of the bar used in Fig. -2 t'or producing a direct drive.

In constructing a wheel embodying the invention it is aimed to produce a wheel that may be connected with a source ot' power in a plurality of ways. Means are provided which will connect the wheel directly with the power and other means are provided which will present multiplying mechanism whereby the wheel will rotate at a slower speed but with greater power than when driven directly.

Referring to the accompanying drawings by numerals. l indicates a rim ot any desired kind and 2 spokes which are connected with hub 3 in any suitable manner. The hub 23 is provided with a be: ring portion l having an overhanging flange 5. said bearing portion 4 resting upon an antitriction ring (3 which in turn rests upon a bearing portion Specification of Letters Patent.

T ot' the casing S, which casing is also provided with a flange t). The casing S 1s bolted or otherwise rigidly secured to the hollow-shaft It), which shaft carries a driving axle 11.

The hub 3 is provided with inwardly and outwardly extending bosses 12 and 12S. respectively. and also with bosses 1I and l5. respectively. These bosses carry pins 1G, 1T, 1S and 1S). as shown in Fig. 4. on which wheels of various sizes may be mounted. Pins 1G and 17 carry the gear wheels 20 and 2l respectively, when a slower speed is desired than a direct drive will give. \Vhen a direct drive is desired the bar '22 shown in detail in Fig. is used. This bar is provided with apertures ;)f and 24 fitting over the pins 1G and 1T. respectively. and also fitting over the end of axle Il to which it is secured by a suitable spline 25. By this construction and arrangement whenever axle 1l is actuated b v the power means the hub 3 and parts connected therewith will also be actuated. It will be noted that the bar 22 is provided with an elongated hub 2G for properly fitting the end of axle 1l so that the same may be properly held in place by a suitable washer 2T and a nut Q8 ot' the usual type. A member 29 may be used to till the space between hub and the elongated hub 2G. A protecting cap 3() may also be mounted on hub i?) if desired to protect the various parts against dust and other foreign matter.

IVlien it is desired to have a. different speed, as for instance` a speed ot' 1 to Lt. gear wheels 9.() and 21 are utilized which mesh with the pinion 31.. which pinion is connected with the axle 11 in a similar manner to the way the bar 22 is shown connected thereto in Fig. It' a diii'erent speed is desired from that produced by the gear wheels Q0 and '21 a larger pinion 32 is substituted for pinion 31. which larger pinion meshes with the gears 33 and 2.3i. It will be noted that the various outer gear wheels on the various pins It to I9. incluY sive. are adapted to mesh continually with a gear ring or rack 35 rigidly secured to or formed integral with the lasiug S.

In Fig. 'i it will bc observed that the pins 1G and 17 are an equal distance Jfrom the center ot axle l1. while the pins 1H and lil are also an equal distance trom thc center of' axle Il but a ditI'erent distance trom said axle to the pins 1G and 1T. This allows dit'- t'erent size gear wheels to be arranged on the different pins and on the axle for changing the speed. It will also be noted that two gear wheels of the same size are used in each instance in the construction shown in Fig. -1 and consequently only two speeds are provided in said structure in addition to the direct drive. y

In Fig. 5 the pins 31S. 3T. 3S and 39 are all spaced different distances from the center of axle 11 whereby a new gear or pinion must be placed on axle 11 each time a different pin is used; for instance, as shown in the drawings, the pin 36 is used with a wheel that will produce a speed of about l to 4. whilel the gear on pin 3T will produce a speed of about 1 to 3, and the gear wheels on pins 38 and 39 will produce a speed of from 1 to 2 and 1 to .3. respectively. It is evident that these speeds may be varied without departing from the spirit of the invention and are merely given as illustrat-' ing the adaptability of the structure for producing any speed desired. It is to be. noted that in this form of the invention the drive is through the gear mounted on axle 11 and one of the gears mounted on pins 36 to 39, inclusive.

By arranging the parts as shown in Fig. 2 a direct drive may be produced, while if the parts are arranged as shown in Fig 4 a 2-speed drive may be produced. As shown in Fig 1, it is intended to illustrate the fact that a large number of speeds may be se cured by merely rearranging the position of the pins carrying the outer gear wheels. The adjustability of the drive is such that any desired speed may be secured but the parts cannot be adjusted for changing the speed while the wheel is in use, In order to change the speed the wheel must remain stationary while the various gears are being interchanged. This will allow the device to be used on tractors for plowing or tractors for pulling loads along the road or any other suitable place where a considerable power is desired and where various speeds may be utilized.
